Pocket Mechanism - Trammel of Archimedes
This is the first instalment of the Pocket Mechanism Series!
It's quite addictive to play with, and there's a certain beauty in the many moving parts and how they oscillate in time. It's made up of three different parts which are all print-in-place, and require no support. Simply insert the three pellets into their individual tracks on the hub, and press fit the handle onto the three pellets.
I would greatly appreciate a Thingiverse Tip from you as this series took quite a bit of trial and error, effort and time.
